With data visualization, you get a visual summary of information; with charts and graphs, it's easier to identify patterns and trends than looking through thousands of rows in a dataset. Along with the bar chart, the line chart is the most popular one.
Line charts are mostly used for numerical and time-series data; to track changes and trends over time, to display forecast data and uncertainty, to identify relationships between 2 or more variables, etc.
In Graphite, a line chart can have more axes like a bar chart: one x-axis (Category) and several y-axes (Series). Also, there are 4 types of lines: basic line, curved line, stacked line, and step line. Sometimes there is a need to put many lines onto a single line chart. But be careful: if the lines are similar, it will be difficult to see the details and differences in the chart. On the other hand, if the lines are well-separated, you can plot all the Series you want to track.
Follow these simple steps:
Collect data and dig into data visualization. With line charts, you can provide a quick analysis of your data. Enjoy! 🙂
